The purpose of the study was to investigate mental health and mental
well-being in a group eating LCHF (Low Carb High Fat). In the study, 246
people recruited from interest groups about LCHF on Facebook
participated. The participants were divided into two groups by how strictly
and how long they had eaten LCHF. The study was conducted as a
questionnaire survey. Mental well-being and impaired mental well-being
were investigated with GHQ-12. Mental health status was investigated with
self-assessed retrospective pre- and post-measurement. The results of
impaired mental well-being were compared with the The Public Health
Agency of Swedens national population value.
The results showed that both LCHF groups estimated their mental
health status significantly better after LCHF diet than before. The entire
LCHF group estimated its impaired mental well-being significantly better
than the Swedish population. The results indicate that LCHF diet has a
positive impact on mental health and well-being.
